The overlay layer is the top-most component of a laminate plank. It consists of a specialized cellulose paper impregnated with melamine resins and often fortified with aluminum oxide particles, one of the hardest known materials. This layer determines the wear rating of the floor. By acting as a tough, clear barrier, it protects the photographic decorative print from fading, wear, and moisture penetration, ensuring the floor maintains its visual aesthetic under normal foot traffic conditions.
